Which of the following describes why a standardized taxonomic system is important?
A classification scheme makes sense of the vast diversity of organisms all around us
When identifying organsims, it is helpful for them all to have a scientific name in the Greek Language
When studying organisms, it is much simpler to be able to classify them into one of two kingdoms
A common system allows all organisms to have a scientific name based on their class and order
The most widely accepted classification system groups organisms into six kingdoms. What is the most appropriate kingdom classification for an organism that is multicellular, photosynthetic, and eukaryotic with cell walls containing cellulose?
Archeabacteria

The gray squirrel, Eastern fox squirrel and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?
To prevent existing named organisms from having their names changed as they become extinct.
To keep the classification system from being altered as new organisms are discovered.
To allow organisms to be placed in many classification levels at the same time.
To standardize the naming and organization of organisms to avoid confusion.
Organisms are classified today using the Linnaean system, and the following table shows the taxonomic classification of two marine organisms living along the Pacific Coast. Taxonomic classification is important to marine biologists because it provides a way to –
Prove that marine evolution occurs
Discover and name every marine organism on Earth
Designate Latin as the universal language of marine biology
Identify marine organisms and find evolutionary relationships between them
A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia. Although these organisms belong to the same phylum, they are classified as different –
Families
Species
Kingdoms
Orders
